上海燃料油期货市场有效性的计量实证研究

已有文献对我国期货市场有效性的实证检验主要针对铜、铝等金属期货,而我国燃料油期货市场是一个快速发展的新兴市场,在国际市场上的影响力正逐步增大。因此运用ADF单位根检验、JJ协整检验等时间序列计量分析技术,对上海期交所燃料油期货市场的有效性进行实证研究有助于我们提出进一步发展的政策建议。结果表明:沪燃料油期货市场已达到弱式有效,当时间跨度在两个月以内时,燃料油期货价格与现货价格存在协整关系。     

上海黄金期货市场有效性的实证分析

黄金因为其兼有货币、商品和金融三大属性的特征历来受到人们的重视。今年年初黄金期货在上海期货交易所的上市,填补了我国长期缺乏金融期货的空白。同时管理层与市场各参与主体对黄金期货给予很高的期望与关注,因此研究上海黄金期货市场的有效性具有重要意义。通过运用ADF单位根检验、协整检验、误差修正模型以及格兰杰因果检验等时间序列与计量经济方法,对上海期货交易所黄金期货市场的有效性进行实证分析。结果表明,上海黄金期货市场尚未达到有效,并且黄金现货价格单向引导期货价格。     

香港期货市场管窥

香港期货市场管窥牧野香港期货市场产生于本世纪７０年代中期，迄今不足２０年的时间，就一路成为美国、英国、日本、新加坡共同构成的世界五大主要期货交易所之一。目前，香港金融期货市场仅次于美国，黄金期货也列世界每三位。为规范有序地发展和完善我国快速成长的期货...     

论我国黄金期货价格发现功能

本文利用协整检验、Granger因果关系检验等方法对我国黄金期货市场与现货市场之间的动态关系进行了实证研究,结果显示:我国黄金期货市场和现货市场之间不存在长期均衡关系,并且二者不能相互引导,我国黄金期货市场尚不具有价格发现功能.     

重大风险事件对中国商品期货市场的冲击效应——基于学生分布的随机波动模型

为检验重大风险事件对我国商品期货市场的冲击效应,本文在构建基于重大风险事件的随机波动模型的基础上,运用贝叶斯MCMC推断技术对中国商品期货市场进行了实证研究。实证结果表明:经济事件、政治事件和自然灾害对中国商品期货市场的收益和波动均存在显著的冲击,并且,"利好事件"和"利空事件"对收益和波动的影响均具有显著的不对称特征;相对而言,各类事件对期货市场影响的显著性、程度和方向既存在一定共性,也具有个体差异。     

螺纹钢期货市场功能的实证检验

上海螺纹钢期货市场的巨大持仓量、成交量,表明其市场功能很可能得到了充分发挥。文章针对螺纹钢期货市场应有的套期保值、价格发现、套利功能,选择相应期、现数据进行了实证检验。检验结果表明:市场具备良好的套期保值效率,存在较为明显的跨期套利机会,期货价格对现货价格具有较强的引导作用。     

沪深300股指期货与现货市场联动性研究

股指期货本身作为一种风险管理工具,在规避风险、对冲,价格发现,套期保值方面有较为重要的作用。2010年4月沪深300指数期货在上海金融交易所正式上市,中国股票市场也逐步同国际接轨,用期货市场合理引导现货的价格走势。本文基于IF0001股指期货和沪深300指数的日收盘价数据,运用EVIEWS软件,对这两个指数进行ADF检验,协整检验以及Granger因果检验,试图发现股指期货市场与现货市场之间的联动关系,结果发现股指期货和现货指数存在长期稳定关系,但并不存在相互引导关系,理论上的公式不成立。     

国内外期货市场之间波动性溢出效应——基于沪铜和美铜的实证检验

本文用BEKK多元GARCH模型对国内外期货市场之间的波动性特征以及波动溢出效应进行实证检验。结果证明:国内期货市场对国外期货市场存在显著的波动溢出效应,与此同时,国外期货市场也对国内期货市场有着显著的波动溢出效应。     

制约我国期货业发展的因素分析

期货市场是进行期货交易的场所。是期货交易的网络和体系。其具体运作是交易者委托经纪公司为代理，在交易所内按照一定的规则，通过公开、平等的激烈竞争来进行的标准化的期货合约买卖。西方国家的期货市场产生100多年来。经过不断的变革和完善，其组织结构与操作方式已实现了规范化、制度化和法律化，有力地促进了期货市场的发展，保证了期货市场的正常运行。但是，我国期货市场在试点过程中。由于缺乏相应的法律法规和统一监管，期货市场在运行中暴露出许多问题。如一些部门和地方竞相兴办期货交易所和设立期货经纪公司；一些企业和个人盲目参与期货交易；交易品种设置不合理、期货合约设计缺乏科学性；期货市场监管不力、期货交易中不规范的行为大量存在；期货市场政出多门、立法滞后；盲目开展境外期货交易。使国有资产大量流失；一些以骗钱为目的的地下期货经纪公司活动猖獗。引发一些经济问题和社会问题。对此。有些人提出期货市场不适应中国，甚至还有人认为期货市场人为盲目地发展。且条件不成熟等。其实。我认为，期货市场不是人们主观愿望所决定的，而是社会主义市场经济发展的必然选择。有其存在的合理根据和客观基础。     

高温煤焦油加氢生产燃料油的工艺调整

由于高温煤焦油加氢生产燃料油的工艺十分的复杂，而且其生产条件也比较苛刻，因此我们在高温煤焦油加氢生产燃料油时，就采用相应的技术手段来对其生产工艺进行适当的调整，这样不仅有效了降低高温煤焦油加氢生产燃料油的难度，还有利于对生产成本的控制，而且大幅度的降低了人们在燃料油生产过程中的危险性，使得整个高温煤焦油加氢生产燃料油工艺可以安全、经济、快速的进行。现通过对高温煤焦油加氢生产燃料油生产工艺和相关整改的内容进行介绍，讨论了其生产工艺在整改以后，轻质燃料油生产的实践结果，以供相关人士参考。     

Crack spread hedging: accounting for time‐varying volatility spillovers in the energy futures markets

Crude oil, heating oil, and unleaded gasoline futures contracts are simultaneously analysed for their effectiveness in reducing price volatility for an energy trader. A conceptual model is developed for a trader hedging the ‘crack spread’. Various hedge ratio estimation techniques are compared to a Multivariate GARCH model that directly incorporates the time to maturity effect often found in futures markets. Modelling of the time‐variation in hedge ratios via the Multivariate GARCH methodology, and thus taking into account volatility spillovers between markets is shown to result in significant reductions in uncertainty even while accounting for trading costs.

基于风险事件的期货市场环境分析及对策

本文通过分析近年来期货市场发生的风险事件,研究得出期货市场环境的不完善,即期货交易法律法规建设滞后、公共信息缺乏以及现货市场化水平低下等,是一系列风险事件发生的诱因。文章认为,完善市场环境是发展我国期货市场的必然要求,也是期货市场功能有效发挥的有力保证。     

The influence of ETFs on the price discovery of gold, silver and oil

In this study we examine gold, silver and oil exchange traded funds (ETFs) and their relation to their respective futures instruments and underlying commodities by using intradaily data. We find that the gold, silver and oil ETFs closely track the performance of their underlying assets by using tracking error and pricing deviation metrics. It has been documented in the finance literature that price discovery occurs in the futures market. We test whether in recent times the existence of ETFs has changed the dominating role of the futures market in price discovery. We find that the availability of ETFs has shifted price discovery for gold and silver to the ETF market, while the oil market has price discovery occurring still predominantly in the futures market.     

OPEC news and predictability of oil futures returns and volatility: Evidence from a nonparametric causality-in-quantiles approach

This paper provides a novel perspective to the predictive ability of OPEC meeting dates and production announcements for (Brent Crude and West Texas Intermediate) oil futures market returns and GARCH-based volatility using a nonparametric quantile-based methodology. We show a nonlinear relationship between oil futures returns and OPEC-based predictors; hence, linear Granger causality tests are misspecified and the linear model results of non-predictability are unreliable. When the quantile-causality test is implemented, we observe that the impact of OPEC variables is restricted to Brent Crude futures only (with no effect observed for the WTI market). Specifically, OPEC production announcements, and meeting dates predict only lower quantiles of the conditional distribution of Brent futures market returns. While, predictability of volatility covers the majority of the quantile distribution, barring extreme ends.     

The role of oil futures intraday information on predicting US stock market volatility

This study investigates the role of oil futures price information on forecasting the US stock market volatility using the HAR framework. In-sample results indicate that oil futures intraday information is helpful to increase the predictability. Moreover, compared to the benchmark model, the proposed models improve their predictive ability with the help of oil futures realized volatility. In particular, the multivariate HAR model outperforms the univariate model. Accordingly, considering the contemporaneous connection is useful to predict the US stock market volatility. Furthermore, these findings are consistent across a variety of robust checks.     

基于分形理论的原油期货高频交易风险测度研究

为了捕捉原油期货高频波动规律,采用WTI原油期货五分钟数据,基于分形理论分别构建GED分布和Skew-t分布的FIGARCH、FIAPARCH和HYGARCH模型,分析其波动特征并对风险进行测度。结果显示：三种模型均较好地刻画出WTI原油期货波动的长记忆特征;基于Skew-t分布的HYGARCH模型在度量原油期货高频交易风险时尤为精确;多头与空头头寸的VaR呈现非对称性;套期保值者或高频交易者可依据模型预测波动率,防止短期波动率过大导致保证金不足而被强制平仓。高频交易在提高市场流动性和拓宽市场深度方面具有一定的作用,因此,在风险可控的条件下,政府应该鼓励高频交易,促进我国衍生品市场繁荣发展,并增强衍生品市场稳定性和国际竞争力。     

涨跌停板制度对期货市场价格发现过程及波动性的影响--基于上海期货交易所的实证研究

本文通过检验在出现涨跌停板之后一个交易日的期货价格及其波动性的变化情况，研究了涨跌停板制度对上海期货交易所期货价格变动的影响。研究结果显示，对不同的期货品种，涨跌停板制度的影响存在一定的差异，但总体而言，涨跌停板制度并没有起到防范价格过度反应和降低市场波动性的作用。相反，在一定程度上延缓了期货市场价格发现功能的发挥，增大了市场的波动性。     

Forecasting oil futures market volatility in a financialized world: Why speculative activities matter

We analyze the relation between volatility and speculative activities in the crude oil futures market and provide short-term forecasts accordingly. By incorporating trading volume and opening interest (speculative ratio) into the volatility dynamics, we document the subtle interaction between the two measures of which the volatility-averse behavior of speculative activities plays a considerable role in the market. Moreover, by accounting for structural changes, we find significant evidence that this behavior currently becomes weaker than in the past, which implies the oil futures market is less informative and/or less risk-averse in recent time period. Our forecasts based on these features perform very well under the predictive preferences that are consistent with the volatility-averse behavior in the oil futures market. We provide discussions and policy inferences.     

Investor sentiment and energy futures predictability: Evidence from Feasible Quasi Generalized Least Squares

Contributing to the budding literature on how emotional and sentimental actions impact the performance of financial markets, this study examines the predictability of energy futures prices with investors’ sentiments. In particular, we examine which of the three (neutral, bear and bull) investors’ sentiments offer accurate forecast information on four energy futures prices. Using the predictability test proposed by Westerlund and Narayan (2015), we discover that all the forms of investors’ sentiments are significant predictors of the movements in energy futures prices. However, the bear sentiments outshine other variants in the forecast of crude oil futures prices, while the bull sentiments provide the most accurate forecast information for the remaining energy futures prices, namely heating oil, gasoline and natural gas. We also find this evidence consistent even when asymmetries are considered in the predictability models. Among other implications of these findings, investors in energy futures and portfolio managers are expected to consider often emotional perceptions in their portfolio constructions and the predictability of future gains.
